NEC Corporation announced on March 5 the development of a new ultra-thin, 0.3mm thick, organic radical battery (ORB) that is compatible with standard IC cards of 0.76mm thickness. These new, 0.3mm batteries are less than half the thickness of existing units.
The size reduction is accomplished by using printing technologies to integrate circuit boards with batteries. As a result, IC cards embedded with these batteries can be used for a wide range of functions, including displays, transmission and advanced encryption processing. Conventional ORB‘s have a thickness of 0.7mm which makes them difficult to combine with IC cards of standard 0.76mm thickness.
